application filed March a, 1919. Serial No. zeroes.

To all whom it may concern Be it known that I, WILLIAM H. Ilor'n, a citizen of the United States, resid1ngat Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Cloth or Paper Printing Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in 'cloth or paper printing machines, and the primary 0 ject of the invention is to provide a machine of this type which may be used for duplex printing or for printing on but one side of the cloth or paper.

A further object of the invention is to provide a machine which may be used to print on one side of each of two different rolls of paper or cloth.

Further and other objects will be later set forth and of themselves manifested in the course of the following description.

In the drawings The figure is a vertical sectional view of the invention, parts bein broken away.

In proceeding in accor ance with the present invention, a series of pairs of printing rolls 1 are employed, the rolls of the pairs being disposed in diametrically opposed relation. These rolls maybe made of wood, or metal, and are preferably mounted on pivoted or swinging arms 2, so that the rolls will respond to the action of gravity in a direction toward one another, the purpose being to cause the rolls to thus bear against the material being printed and to each exert pressure in an opposite direction against the other so as to increase the printing pressure and thus provide a better impression.

The printing rolls are engaged by color topping rolls 3, whichlatter in turned are engaged by color furnishing rolls a, the latter being partly submerged in the color in the color boxes 5. It will be obvious that any number. of the printing rolls may be used, the drawings depicting five pairs, though the inventionhas'nothing to do with the number of such pairs which may be increased or decreased as desired or found necessary.

-An' endless apron 6 is trained around four pulleys 7 which latter are arranged so that the apron has a flight between the opposed printing rolls 1, while rolls 8-8 carrying the cloth or paper and similar rolls 9-9 over which the paper or cloth after printing roll 9 are disposed on each side of the verti- 1 ca] flight of the apron between the rolls l-1.

In operation assuming cloth from the rolls is to be printed on one side of each, then the endless apron is employed and the cloth passing from the rolls 8-8 will be engaged with the respective opposite sides, of the apron and will be printed on but one side, namely the side farthest from the apron. In this operation it will be apparent that two rolls of cloth are being simultaneously printed each on one side only. If it is desired to use the machine for duplex printing, then the apron is removed, and cloth is led from but one roll 8 to its companion roll 9, the cloth from the other roll being disposed out of printing position, so that in passing upwardly between the various printing rolls 11 the cloth or paper will be simultaneously printed on each of its two sides. The apron may be made of rubber, or cotton, or other flexible material suitable for the purpose. The cloth or paper after leaving the rolls 9 may be led to any desired point for drying and subsequent folding or rolling as desired.

Having thus described myinvention, what I claim as new and desire to secure by Letters Patent is 1. In a cloth or paper printing machine, a series of pairs of opposed printing rolls arranged to have space therebetween in a vertical line, an endless apron having a flight coinciding with said line and disposed so as to be engaged on its opposite side faces by said respective rolls of the pairs of rolls, and feeding rolls located on opposite sides of the lower end of said flight of the apron, one of said feeding rolls being encompassed by said endless apron.

2. In a cloth or paper printing machine, a

series of pairs of opposed gravity responsive printing rolls arranged in a vertical line, and

an endless apron having a flight coinciding with said line and disposed so as to be engaged on its opposite side faces by said respective rolls of the pairs of rolls, and feeding rolls located on opposite sides of the for duplex or single surface printing, a seriesing rolls and to cause said a ron to encompass. an upper. and a lower abric carr ing roll on the same side of the printing ro Is.

4:. In a cloth or paper printing machine of pairs of printing rolls, the rolls of the pairs being disposed in opposed relation, and

an endless apron having a flight engaged be tween the opposed rolls of the pairs of rolls, whereby sald apron will act to have its 0pposite side faces support two diiferent sheets of material for single surface printing and upon removal of the apron said rolls willsimultaneously print on each of the opposite sides of a single sheet of material, and means to mount the rolls whereby same will automatically be adjusted for duplex or single surface printing.

5. In a fabric printing machine, pairs of opposed printing rolls, an upper and a lower pair of fabric carrying rolls arrangedon oppositesides of the prmtmg rolls, an endless apron, and means to mount the apron so that same has a flight extending between the printing rolls and to allow of removal of the apron so as to permit single surface print .ing by use of but one of each of the fabric carrying rolls of the pairs of the latter. In testimony whereofl have signed my name to this specification in the presence of so two subscribingwitnesses.
